Across the nation, large-scale water infrastructure such as dams have provided a multitude of services, from electric power and water reservoirs to flood control and containment of pollution. But federal investments in large water infrastructure projects have largely been curtailed over the past few decades.
At about 250 lightning flashes per square kilometer per year, the Lake Maracaibo Basin in northwestern Venezuela has the highest annual lightning rate of any place in the world.
A 4,000-foot-high mountainside collapsed in Glacier Bay National Park this week in a massive landslide that spread debris for miles across the glacier below. Scientists at Lamont-Doherty Earth Observatory are studying it to improve understanding of landslide risks.
Karolina Walęcik, a recently graduated MPA-DP student from the class of 2016, spent her summer field placement on a post-earthquake aid transparency project with the Accountability Lab in Kathmandu, Nepal.
Accounting for Volcanoes Using Tools of Economics
Climate scientists teamed up with an econometrics expert to develop an innovative new method for picking out past volcanic eruptions in temperature reconstructions going back millennia and gauging their impact on the climate.
“If climate change is having an impact and is making droughts worse, then we should see this in the record over several centuries—and we do,” said the study’s author, Benjamin Cook.
A new survey of American households finds two-thirds lack adequate plans and supplies for a disaster, and half of them are not confident in the ability of government to meet the needs of children in a disaster.
In studying climate and tropical cyclones, researchers find a weather phenomenon at play.
Using one of the most advanced atmospheric computer models available, scientists compared our expected future with a scenario in which ozone-depleting substances had never been regulated.
Over the last six years, seismologists Göran Ekström and Colin Stark have been perfecting a technique for picking out the seismic signature of large landslides. They just discovered North America’s largest known landslide in many years – 200 million tons of sliding rock in Alaska.
